Experts say the pattern reflects long-standing geological features rather than any change in underlying risk
More than 300 earthquakes were recorded in the UK in 2025, according to data from the British Geological Survey, with activity spread across much of the country and clusters in known seismically active regions. Up to 18 December, a total of 309 earthquakes were logged, averaging close to one event a day, although only a small fraction were strong enough to be noticed by people.
The largest earthquakes of the year occurred just hours apart near Loch Lyon in Perth and Kinross, Scotland. A tremor measuring 3.7 on the magnitude scale was recorded on 20 October, followed shortly afterwards by another measuring 3.6. The area remained active in the weeks that followed, with the BGS reporting that 34 earthquakes in total occurred near Loch Lyon between October and December.
Scotland featured prominently in the annual figures, particularly Perthshire and parts of the western Highlands, which recorded the highest concentration of earthquakes overall. Southern areas of Wales also saw notable levels of seismic activity, along with parts of northern England, especially Yorkshire and Lancashire. By contrast, some regions experienced very little movement over the course of the year.
On average, the UK experienced an earthquake “almost once a day” in 2025, according to seismologist Brian Baptie. He said the pattern of activity reflected well-understood geological processes rather than anything unusual. “The west of Scotland is one of the more active parts of the UK,” Dr Baptie said, pointing to the presence of major geological faults that run through the region.
Some of the seismicity in Scotland can be attributed to ancient fault systems such as the Great Glen Fault and the Highland Boundary Fault, which continue to adjust under present-day stresses in the Earth’s crust. These faults, formed millions of years ago, remain zones of relative weakness where small earthquakes can occur. “By contrast, north-east Scotland experiences very few earthquakes,” Dr Baptie added.
In England, Lancashire experienced a brief cluster of activity towards the end of the year. Two minor earthquakes struck the county in as many weeks in December, with one tremor measuring 2.5 in magnitude. The epicentre of that event was located off the coast of Silverdale in Morecambe Bay. The BGS confirmed that this quake was an aftershock of a larger 3.3 magnitude earthquake that had hit the same area at the start of the month.
Across the UK, seismic activity is tracked by a network of around 80 monitoring stations operated by the BGS. These instruments are sensitive enough to detect very small movements in the ground, many of which go unnoticed by the public. The organisation said the UK typically experiences between 200 and 300 earthquakes each year, but only around 20 to 30 of them are usually felt or heard by people.
Despite most earthquakes being minor, public awareness remains high. During 2025, the BGS received 1,320 reports from members of the public who said they felt tremors. These reports help scientists to understand how ground shaking is experienced in different locations and how it correlates with instrumental measurements.
Historically, moderate earthquakes are relatively rare in the UK. A magnitude-four event in the UK and surrounding areas is typically recorded every three to four years, while a magnitude-five earthquake tends to occur only once every few decades. The most recent magnitude-five event struck in 2008 near Market Rasen in Lincolnshire, causing minor damage to buildings and being felt across a wide area.
Larger earthquakes are much less frequent. A magnitude-six earthquake is expected only once every few hundred years in the UK. The largest known earthquake to affect the country occurred in 1931 near the Dogger Bank in the North Sea, off the coast of Yorkshire. That earthquake, measuring 6.1 in magnitude, was powerful enough to cause minor damage to buildings along the east coast of England, despite its epicentre being around 60 miles offshore.
In general terms, earthquakes are caused by the movement of tectonic plates that make up the Earth’s surface, as they push against or slide past one another. Smaller earthquakes, such as those experienced in the UK, are typically caused by movements along faults within the Earth’s crust rather than activity at major plate boundaries.
